When the relay is energized,

the indicator goes on.

•

Relay coils less than

100V DC do not contain a

protection diode (except

DPDT).

•

Relay coils below 100V

use LED indicator, coils

above 100V use neon lamp

indicator.

Contains a diode to absorb the back emf

generated when the coil is de-energized. The

release time is slightly longer. Available for DC

coil only.
